CONTROLLING MECHANISM FOR GLASS-FURNACES.

applied to'the spout of a glass furnace;

Fig, 2 is a front elevation thereof; Fig. 3 is a plan, and Fig. 4 shows details 'of the orifice for the spout. In Fi 5 I have shown the form of gate usua y employed for flowing glass from furnace spouts.

My invention relates to gates for spouts of glass furnaces, which are used for flowing a continuous stream of glass to molds or other receptacles. My invention consists in providing the end of the delivery spout with a bushing andin regulating the supply o lass passing through bushing byanf adjustable gate, thus providing an opening.

from the furnace, the size ofwhich can be regulated at will and which I have found to be very durable and to be easily repaired.

invention provides a gate very simple in construction and operation and one Which is very dependable and prevents the unexpected cutting ofi of the stream inherent in the gates now in. use. Myinvention also conslsts 1n the 'COHStlUCtlOIl and opera.-

tion of the various parts which I shall here-- inafter describe and claim.

the glass is flowed, and 0 indicates the normal level of the lass inthe "furnace and spoutrsThe endo? the-spout B is provided with a ,claybushing 2; having an orifice 3 toz-permitthe' flow ofglass therethrough.

- ,7 7 Thelclay bushing'fl is mounted and carried 7 115 onacast iron frame 4 and is held-in. posiition by'the plate orband a which bears against the upper surface of thebushing and is secured to the frame 4' by suitable bolts, Positioned on the clay bushing 2*is a water-cooled ing. Water for cooling the gateis supplied throughthehose connection 6. The gate 5 Specification of Letters Patent. PatentedMay 14, 1918,

Application filed September 8, 1914. Serial No. 859,986.

gate 5, adapted to ,re late the size of the aperture 3 in the clay ush is carried by the rod 7 which-seats in openings in the housing 8. Secured to therod 7 is a block 9, held loosely in'position thereon by the collars 10. Connected to the block 9 V are the links 11 which, at their other ends,

are secured to one end of the lever'12 which has a fulcrum 13 on the housing 8. 'At the end of the lever 12 remote from the links 11 are the links 14, which connect'thelever to a screw stem 15 which seats in apertures in the housing 8 and has a threaded engagement with the regulator wheel 16. which is positioned between the arms 17 of the housmg 8. t

The housin 8 is mountd on a pivot pin 18 seated in t e frame 4, so that the gate 5, mounted on the housing 8, will always 'be spring-pressed against the bushing 2 by the] spring 19. The spring 19, which is mounted on a rod 20 secured to the housing 8, bears at oneend against an extension 21 of the frame 4, and at its other end against an. ad-

justingnut 22 by which the compression of the spring may be regulated as desired. I

To permit the flow of glass from the spout B, the operator manipulates the regulator wheel 16, causing the screw stem 15 to be moved downwardly, thereby raising the gate 5 through the lever 12 and rod '2'.

When the stream of glass is flowing from the furnace spout, -mam'pulation of the wheel 16 will permit exact stream of glass to be obtaine In Fig. 5 I have shown a furnace spout B equipped with the usual clay bushing 23 through which the glass-flows. A clay plug Referring-tojthe drawings, A is the furnace, B is'the furnace spout through which 24'is used to regulate the sizeof the a 'ture in theclay bushing-23 and to out oifthe supply of glass fiowin therethrough when" desired. I have foun that the bushing 23 usually lasts about one week, and the life of the clay plug 24 is extremely variablegillation of the or more. The water cooled gate 5 is durable and needs renewal at very infrequent intervals.

It is obvious that various modifications may be made in the device which I have shown and described herein without departin from my invention.

hat I claim is:

1. In an apparatus for flowing molten glass from a furnace or the like, a delivery spout, a clay bushing having an orifice therein through which the glass flows, and

a water-cooled gate adapted to be moved. across said orifice for regulating the flow of glass therefrom, the said gate having a pivotal mounting, the said mounting having spring mechanism for pressing the gate against said bushing. v

2. In apparatus for fiowin molten glass from a furnace or the like, a elivery spout, a clay bushing about an orifice in the spout through which the glass flows, a water-cooled gate, mechanism for moving said gate across said orifice, and resilient means mounted in said mechanismremote from the gate for causing the mechanism to force the gate against the bushing.
